| At certain times, Saturn's auroral ring is more like a spiral, its ends not connected as the energy storm circles the pole. |
|
| The HAARP antenna as is it now configured modulates the auroral electrojet to induce ELF waves and thus could have an effect on the zonal winds. |
|
| If analogous resemblances can be traced between hyetal and auroral curves, they will be interesting and suggestive. |
|
| A few years ago it was suggested that auroral phenomena could exist on Mars too. |
|
| Nevertheless, the potential exists for periods of strong auroral storm conditions developing during the next several days. |
|
| Vivid red auroral rays glowed over all over North America, stretching as far south as Arizona, southern California, Mississippi, and Texas. |
|
| Super-energized particles from the radiation belts and from auroral storms can damage the sensitive electronics of satellites. |
|
| People as far south as Virginia were treated to fantastic auroral displays in the night sky. |
|
| This eruption may cause auroral displays and magnetic storm activity when it impacts the Earth's magnetic field sometime Friday. |
|
| Synoptic view of the propagation of the shock and its auroral consequences. |
|
| This link was already shown in the case of the Earth via measurements of satellites just above the auroral regions. |
|
| The variations of the auroral activity, observable remotely, are thus a diagnosis of the global magnetospheric activity. |
|
| Ionospheric side-scatter from F-region irregularities located in the auroral regions has been reported by several workers. |
|
| The display ends with a poleward retreat of the auroral forms, the rays gradually degenerating into diffuse areas of white light. |
|
| The storm, which occurred on Sept. 2, 1859, produced intense auroral displays as far south as the tropics. |
|
| During a typical three-hour substorm, the aurora near midnight exhibits a sequence of changes called the auroral substorm. |
|
| For about an hour afterward, bands of quiet auroral arcs drift equatorward near midnight in the northern and southern auroral ovals. |
|
| The auroral radio emission of giant planets are usually used to estimate their rate of internal rotation. |
|
| Charting the auroral changes can protect Earth-based electrical, navigation, and communications systems from the disruptions that space storms cause. |
|
| The highest geomagnetic activity is observed in the auroral zone. |
|
|
|
| Because of our location on the Earth, Canada experiences the best auroral displays in the world and has had several satellites designed to study the science behind the displays. |
|
| The instruments of the two probes then could measure an intensification of the radio and UV auroral activity of Jupiter, correlated with the impact of these shocks on the Jupiter magnetosphere. |
|
| The peak of North Dakotan auroral activity appears to take place after sunspot maximum and when the spots are declining. |
|
| His career in theoretical physics started in space, with polar and auroral electrojets, later going to parametric instabilities and laser theory. |
|
| Geomagnetically he is closer to the auroral zone than the United Kingdom and is much better placed to ob serve this phenomenon. |
|
| At this time of year the aurora borealis can occasionally be seen on the northern horizon during moderate auroral activity. |
|
| Left-hand column: images of the CME and the auroral emissions of the Earth, Jupiter and Saturn at the times indicated by the red arrows, during and after the end of the passage of the shocks. |
|
| The comparison between UV and radio auroral emissions on planets is very difficult, because the radio observations do not have much angular resolution at kilometric wavelengths. |
|
| In fact, the precipitation of oxygen ions from the Jovian magnetosphere in the auroral regions may lead to the formation of water vapor and OH radicals. |
|
| Eruptions on the Sun send out clouds of plasma that interact with the Earth's magnetic field producing magnetic storms, ionospheric disturbances and auroral displays. |
|
| In Canada, we build and use auroral imagers, magnetometers and ionospheric radars, as well as satellite and rocket instruments for studying the aurora. |
|
| This plasma injection results in intense auroral displays in the polar regions, while the contractions are observed on Earth as a severe magnetic disturbance known as a polar substorm. |
|
| For example, recognizing that solar storms and auroral displays are likely to make the news sometime during the IPY, prepare a briefing package and list of researchercontacts ahead of time. |
